Electrobat, a battery manufacturer, is investigating how storage
temperature affects the performance of one of its popular deep-cell
battery models used in recreational vehicles. Samples of 30 fully
charged batteries were subjected to a light load under each of four
different storage temperature levels. The hours until deep
discharge (meaning ≤ 20% of charge remaining) were measured. The
data is shown in the accompanying table.
